Greetings,
Vitagenesis looks like another penta water type company, works good, but wary expensive.
www.ObeyNature.com can into great detail about water, and the best form of water is from fruit or vegetables. The next best is distilled water flavored with lemon or honey ar what ever to add the nutrients. I go a step further and charge the dyne level and or bovis units in the water.
As far as growing hair is concerned, I have heard the most natural success stories with the five tibetan rites.
www.srimadbhagavatam.org and see the art gallery that has a yogi meditating underwater for a long time.
